Whiteline Complete Watts Link Rear Suspension (05-14 Coupe)

Video Review & Installation

Hey I’m Justin with AmericanMuscle.com, and I have with me possibly one of the best live axle handling modification you can do, thanks to Whiteline’s Watts link rear suspension setup, fitting all 2005 and newer Mustangs. The Mustang’s solid rear axle has unfairly been the subject of much criticism over the years, and is oftentimes considered to be the weak point of handling performance. The truth is, the modern live axle can be just as good as an independent rear setup, given a little help, that help comes in the form of this Watts link from Whiteline. The Watts link is designed to replace the factory Panhard setup in your Mustang and prevent any lateral or side to side movement of a rear axle. Even though the Watts link and the Panhard bar are essentially one of the same, the Watts link is a far superior design. The Panhard bar mounts to one end of the chassis, and connects to the far side of the axle, and while yes, this does do a great job of preventing any lateral movement, the Panhard bar does have one flaw, vertical movement. When the suspension moves up and down, the Panhard bar has the tendency to move in an arc, rather than up and down, this can result in an varying roll center which basically translates into less handling predictability, coming into or out of a turn. The design of Whiteline’s Watts link allows the rear axle to move up and down, thanks to these 2 arms that mount to each side of the chassis, and pivot right here at the diff cover. This allows the roll center to remain constant no matter what the car is doing, turning, centering, it all translates to increased handling predictability, and a more stable, planted rear end. Taking a closer look you can see this total package from Whiteline is no joke, almost the entire thing has been constructed using quality 4130 chromoly steel, and features Whiteline’s unique elastomer bushings. Perhaps one of the biggest features of this kit besides the full adjustability, is the fact that it includes a brand new diff cover, making this product a 100% bolt on affair. Because this kit does bolt on, the install really isn’t all that bad, and can be accomplished in the garage on a Saturday or Sunday afternoon. Keep in mind, since the factory diff cover will be coming off, make sure you have a drain can on you to capture all that fluid when you do crack the pumpkin. With that said, make sure you have a couple of quarts of fluid to fill the diff back up when everything is installed. When it’s all said and done, you should be wrapped up in about 4 or 5 hours. So if you’re the type of Mustang owner who prefers the twisty back roads or autocross track to the drag strip, and you want to take your live axle car to the next level, then be sure to check out this complete Watts link system from Whiteline, available right here at AmericanMuscle.com
